I'm also a Relay user. I had been using the free version for several years. When it looked like Relay was going to go under like the rest, I felt bad and paid for Pro as a thank you. So now I still have use of it, but sure how long that will last.
I stopped going to Reddit in mid June except for one very small private sub. I figure being private means Reddit doesn't get much from my visits there. If I lose access to Relay, I'll probably stop totally though - not sure I could switch to the web interface and I'm not going to install their app.
